    Hi. I just got my laptop for about 3 months. I haven't installed much apps yet. But since yesterday I noticed that my screen brightness can not be adjusted.

     

    When I use the shortcut Fn + left arrow/right arrow it alternates between two levels but it does not change anything. I have also tried to change it in different settings like in power options and etc. I noticed that in the PC settings, the screen has this lock icon. I don't know how to unlock it.

    please help me should I install a driver or something?
